1

Which two hormones control the level of glucose int he blood?

Insulin and glucagon

2

What is glucose stored as in animals?

Glycogen

3

How is glucose added to the blood?

Eating Carbohydrates

4

how is glucose removed from the blood?

Cell metabolism, which is faster during exercise

5

Where is excess glucose stored?

In the liver and muscles

6

Why do animals store glucose as glycogen?

It is insoluble and compact

7

Changes to blood glucose concentration are monitored and controlled by which organ?

Pancreas

8

What is Negative feedback?

A response that brings a condition back to its optimum level e.g. insulin release brings glucose down to optimum.

9

When blood glucose levels increase, which hormone is released by the pancreas?

Insulin

10

When blood glucose levels decrease, which hormone is released by the pancreas?

Glucagon
hint: the 'glucose-a-gone'

11

What is the function of insulin?

Causes the liver and muscle cells to remove glucose from the blood and store is as glycogen.

12

What is the function of glucagon?

Causes the liver to convert stores glycogen back into glucose and release it into the blood

13

What is the name of the condition in which affects the persona ability to control blood glucose levels.

Diabetes

14

What are the two forms of diabetes called?

Type 1 and type 2

15

In which type of diabetes does the pancreas produce little or no insulin?

Type 1

16

What does it mean if someone suffering from type 1 diabetes is receiving insulin therapy?

Several insulin injections per day

17

Does a type 1 diabetes patient always inject the same amount of insulin? why?

The amount varies depending on diet and level of exercise

18

A person with diabetes should take into account which two factors in their daily routine (aside from how much insulin they inject)?

Their carbohydrate intake and activity level

19

In which type of diabetes does the person become resistant to their own insulin?

Type 2

20

Does a type 2 diabetes patient still produce insulin from the pancreas?

Yes (it just is not recognised by the body)

21

What is the risk main factors for developing Type two diabetes?

Being overweight (especially obese)

22

How do type 2 diabetes patients usually control their blood sugar levels

Carbohydrate-controlled diet and regular exercise

23

How does someone develop type 1 diabetes?

It is genetic

24

Is diabetes a communicable disease?

No (it cannot be transmitted to those around a diabetes patient)
